Demolition and Precision Materials Blasting

News story of a TechNick blast - 01:21 sec (3.29 mb)

Explosives can be a very effective and safe alternative to mechanical breakage and demolition of structures and strong facilities.

One main advantage of explosives demolitions is that after some engineered pre-conditioning of a high or complex structure, all persons can be removed to a safe distance before activating small explosives charges to complete the final destabilisation of the base of a structure allowing it to topple or crumble to the ground.

From this point a majority of the hazardous, stored potential and gravitational energy has been dissipated and the job becomes one of more simple materials handling and transport.
